On rainy days in January and February, this little bee is the buzzer that's flying around trying to find a dry flower. They seem to get quite irritated, irrationally so, but , with only a million or so brain cells they've not adapted to rain forming drops at the end of the flower tubes on Manzanitas and many Ribes.
